If you have been dealing with thumb pain or rhizarthrosis, you may wonder if your work is making it worse. Some jobs put more stress on your hands than others. In this article, we look at a study that examined how physical therapists experience stress on their bodies during their workday.
Key Findings at a Glance
- Research shows that physical therapists perform many varied tasks that put stress on their muscles, bones, and joints.
- Scientists created a new method to measure how risky these tasks are for the body, looking at force, repetition, and awkward postures.
- According to this study, when assessed properly, the physical risk for therapists was acceptable because the body has enough time to recover between tasks.
- This method can help identify workers who may be more sensitive to overuse injuries and adjust their work to protect them.
Here are the key points we will cover:
- What biomechanical overload means and why it matters
- How researchers measured risk in physical therapists
- What the findings mean for people with thumb pain

What Is Biomechanical Overload?
Let us start with the basics. The term biomechanical overload sounds complicated. But it is actually quite simple.
Imagine lifting a heavy box once. Your body can handle that. Now imagine lifting that same box one hundred times a day, every day. That is overload.
For people with thumb pain or rhizarthrosis, understanding this idea is important. Your thumb joints can experience overload when you grip, pinch, or twist things repeatedly.
When we talk about overload, we are looking at three main things:
- How much force you use
- How often you repeat the same movements
- Whether you hold your body in awkward or uncomfortable positions
You may be wondering why this matters. Here is where it gets interesting.
How Did Scientists Study This?
Researchers in Italy wanted to understand how physical therapists experience stress on their bodies at work. Physical therapists help patients move better after injuries or illnesses. Their job involves a lot of hands on work.
According to this study, the scientists faced a challenge. Physical therapists do many different tasks during their day. One moment they might be helping someone walk. The next moment they might be lifting a patient or bending to assist with exercises.
So the research team created a new method. They called it the Whole Body Risk Assessment Biomechanical Overload, or WB-RAMBO for short.
Breaking Down the Tasks
The scientists took each type of work that therapists do and broke it down into small steps. These are called elementary operations. Think of it like a recipe with individual steps instead of one big instruction.
For each small step, they measured three risk factors:
- How much force the therapist needed to use
- How many times they repeated the movement
- Whether they had to hold their body in awkward positions
They used several different tools and methods that scientists around the world have developed for measuring workplace risks.
Checking the Results
Research shows that the team wanted to make sure their findings were accurate. So they looked at the medical records of the physical therapists. These records came from regular health checks that the therapists received at work.
This gave them a way to compare what they measured with real health outcomes.
What Did the Research Show?
Let us look closer at what the scientists found.
According to this study, the overall risk level for physical therapists was acceptable. This means that while there were some small problems with body positioning and repetitive movements, these were not dangerous.
Why was the risk acceptable? The answer lies in recovery time.
The therapists moved between different tasks throughout their workday. They did not repeat the exact same motion over and over without stopping. Because they switched activities, their muscles and joints had time to rest and recover.
The small stresses that the therapists experienced were spread out. They were diluted across the work shift. This gave the musculoskeletal system the chance to recover properly.
What About Workers Who Are More Sensitive?
Here is where it gets even more interesting for people with thumb pain.
The researchers noted something important. Their method can help identify hypersusceptible workers. These are people who are more sensitive to physical stress because of existing conditions or individual differences.
If you already have rhizarthrosis or thumb pain, you might be hypersusceptible to tasks that involve gripping or pinching. This method could help your employer adjust your work to protect your hands.
Why Does This Matter for Thumb Pain?
You might wonder what physical therapists have to do with your thumb pain. The connection is in the method, not the specific job.
This research shows that scientists can measure the physical risks of complex jobs. They can break down varied tasks into small pieces. Then they can see which movements cause the most stress.
For someone with thumb arthritis, this approach could be used in any workplace. Whether you type on a keyboard, use hand tools, care for patients, or do assembly work, your tasks could be measured the same way.
Recovery Time Is Key
One of the most important findings is about recovery. According to this study, even when there are risky movements, spreading them out over time allows the body to heal between stresses.
If your work involves repeated thumb movements, you need breaks. You need variety in your tasks. This gives your thumb joint time to rest.
Personalized Work Plans
The researchers mention that workplaces can redesign job tasks based on this kind of assessment. They can adapt the work to fit both the company’s needs and the needs of workers who are more vulnerable to injury.
For you, this could mean:
- Requesting a job task analysis if your thumb pain is work related
- Asking for modifications to reduce repetitive gripping or pinching
- Planning your personal activities to include variety and rest
- Understanding that recovery time is not laziness, it is necessary for healing

Frequently Asked Questions
Can my job cause thumb arthritis?
Some jobs that involve repeated gripping, pinching, or twisting can put stress on your thumb joint. Over time, this stress may contribute to wear and tear. However, many factors affect whether you develop arthritis, including genetics and age.
What does it mean if my work has acceptable risk?
According to this study, acceptable risk means that while there may be some physical stress, it is not at a dangerous level. Your body has enough time to recover between tasks. This does not mean there is no risk at all, just that it is manageable for most people.
How can I tell if I need work modifications for my thumb pain?
If your thumb hurts during or after work tasks, or if the pain gets worse on workdays and better on days off, your job may be contributing to the problem. Talk to your doctor about whether work modifications might help. Your employer may be able to adjust your tasks or provide different tools.
Does taking breaks really help prevent overuse injuries?
Research shows that spreading out physical stress over time allows your muscles and joints to recover. Short breaks between repetitive tasks give your body a chance to rest and heal. This can reduce the buildup of damage that leads to pain and injury.
Conclusion
This research gives us a valuable tool for understanding workplace stress on the body. The scientists created a detailed method for measuring risk even in jobs with lots of variety.
For people living with thumb pain or rhizarthrosis, the key lessons are clear. Recovery time matters. Variety in your movements matters. And it is possible to measure and adjust your activities to protect your joints.
If your work or daily activities involve repetitive hand movements, consider how you might add variety and rest periods. If you are experiencing pain, talk to your doctor about whether your activities might be contributing to the problem.
Remember that knowledge is power. Understanding how physical stress affects your body helps you make better choices about work, hobbies, and daily life.
